摘要
文章在传统的灰色模型和马尔柯夫模型的基础上,提出了动态无偏灰色马尔柯夫模型,阐述了该模型的建立方法,并采用这三种模型对我国铁路客运量进行了预测,对比结果表明动态无偏灰色马尔柯夫模型的拟合效果较好,预测精度较高,是一种行之有效的预测方法。
Based on the original Grey model and Markov model,the article introduces CDUBGM-Markov model.It mentions the building process of the model and compared it to other two alternatives.The results show that CDUBGM-Markov has a better simulation ability and it is a suitable tool for projecting.
